I was reading some other threads where Logitech gear was being recommended and wanted to post this for anyone who is into building their own machines. just wanted to share my experience in hopes that it might help someone avoid the same pitfall.

...a caveat involving NVIDIA Surround and Logitech Gaming Software if you're going down that path with your build...

For the most part all of my keyboards, mice, gamepads, speakers etcetera for the last few decades have been Logitech....I have been a devoted fan of their gear. When I built the current machine and was getting it up and running I had some issues with getting NVIDIA Surround working. Turned out to be the Logitech Gaming Software (LCore.exe) that was in conflict with Surround; I could have one or other but, not both. The fixes described on the net didn't work for me either. Not willing to give up Surround I swapped out my Logitech gear for Corsair and Razer gear....problem solved.

Cheers!

Never been a huge fan of Logitech tbh, would sooner opt for Corsair over Razer though. D'ye know if either company has acknowledged this issue yet anywhere?

I have seen nothing official but, on the Logitech home site there is a lengthy forum discussion about it and someone does ask the same question (to which there is no response) :

Is Logitech going to acknowledge the problem?
How about you add a warning label on your product that use Lcore.exe resource so that people don't face the nasty surprise, that would be the responsible thing to do since you can't fix the problem.
Fix problem or add a warning label, support section, be the company you used to be!!!

Apparently there may be other issues associated with the Lcore.exe software as well. If you read the thread they talk about frame rate drops.

In fact the issues are a common thread on a lot of forums. Here's another post from the Logitech site forum :

Re: LCore.exe Interferes with NVIDIA Surround
People around the web with multiple monitor setup experiencing the problem with various games and hardware, the fix is always to kill the "Lcore.exe" which is the Logitech driver...
